I just completed installing my XM Radio into my Liberty. I was stymied about how to get the Satelite antenna on the roof. I discovered I could set it below the roof in the attic space above the TV on the steel frame. I get 100 percent reception! The Antenna is magnetic so it bonds to the steel frame and creates a large antenna grid. Also, I was hesitant in taking walls and dashboard covers apart, but I found it was quite easy as Liberty had made most everything easy to open up.
